In general, larger plants have larger organs. So, one option for increased yields is to breed and grow for the largest size possible. However, there are practical reasons to growing smaller plants. What are some drawbacks to breeding and growing increasingly large plants? List and briefly explain two possible reasons.

Why plant breeders intend to change the inheritance of crop plants? How plant breeders can change the heredity of crop plants? Explain your answer in briefly.
A plant breeder found a species of flowering plant with very attractive flowers growing wild in a field and she thought it would appeal to her customers. Some of the plants of this species had red flowers, some white flowers, and some pink flowers. While she would like to be able to offer her customers all three colors of flowers, she only has permission from the landowner to dig up one plant to bring back to the nursery as breeding stock. What would be the best thing for her to do? Top of Form Take a white flowering plant since the white allele could be masking the pink allelle. Take a pink flowering plant since it is likely to carry both the red and white alleles. Take a red flowering plant since it could produce all three colors eventually. Take a red flowering plant since the red allele is likely the dominant one.

Rice is a staple food in Asia. In the 1950s, Asia faced food shortages and an impending famine. If you have relatives that lived in Asia during the ’50s and ’60s, they may tell you that due to the rice shortage, many starved and those who were lucky had to supplement their diet with other crops, such as barley. In 1962, an organization focused on research and development of rice called the International Rice Research Institute (IRRI) developed a high-yielding variety of rice by crossing the two types of rice from Indonesia and China. The result was groundbreaking. The new variety called IR8 (India Rice 8) increased its yield as much as 10 times the traditional variety of rice. By the early 1970s, many rice farmers in India, the Philippines, and Vietnam switched to cultivating IR8 rice, making these countries into major rice exporters, preventing a mass famine in Asia, and saving millions of lives. In many major Canadian cities, a GMO-free, organic diet is becoming more popular, as can…
A scientist pollinates a true-breeding pea plant with violet, terminal flowers with pollen from a true-breeding pea plant with white, axial flowers. Which of the following observations would most accurately describe the F2 generation? a. 75% violet flowers; 75% terminal flowers b. 75% white flowers in a terminal position c. 75% violet flowers; 75% axial flowers d. 75% violet flowers in an axial position
Different traits may be important in order to increase wheat yield. These traits may include short plant height, short and erect leaves, large and compact panicles, and resistance to shattering. Resistance to shattering is an important agronomic character for maximizing wheat yield, because plants with low susceptibility to shattering have reduced loss of grain mass during harvest. If you have determined that VG = 357, VD = 52, VI = 24 and VE = 5 for the shatter trait, what is the estimate for narrow sense heritability for the shatter trait?
Many beautiful varieties of roses have been produced, particularlyin the last few decades. These newer varieties often have verystriking and showy flowers, making them desirable as horticulturalspecimens. However, breeders and novices alike have noticed thatsome of these newer varieties are not very fragrant compared withthe older, more traditional varieties. From a genetic point of view,suggest an explanation why some of these newer varieties withsuperb flowers are not as fragrant.
From an agricultural point of view, discuss the advantages and disadvantagesof selective breeding. It is common for plant breeders to take two different, highly inbred strains, which are the product of many generations of selective breeding, and cross them to make hybrids. How does this approach overcome some of the disadvantages of selective breeding?
Maize is a highly cross-pollinated crop and heterotic phenomenon is evident from the currently available hybrids. If you are given a huge random germplasm pool of maize, what procedure you will adopt to develop competitive high yielding hybrids.

For each of the following statements, indicate whether the statement describes the P generation, F1 generation, or F2 generation. The plants in the P generationF1 generationF2 generation were allowed to self-pollinate. The plants in the P generationF1 generationF2 generation are true breeding. After a cross, there are three times as many tall plants as there are short plants in the P generationF1 generationF2 generation.
